Extending Local Canonical Correlation Analysis to Handle General Linear Contrasts for fMRI Data

Table 2

Ratio of activations in gray matter and outside of gray matter for different analysis methods. The number in the table is the ratio of the number of voxels detected in gray matter and the number of voxels detected outside of gray matter. Note that the GLM-NS has the highest value because there is no smoothing involved. Compared to fixed Gaussian spatial smoothing (GLM-GS), cCCA-RG yields higher ratios demonstrating less blurring and better confinement to gray matter.

	GLM-NS	GLM-GS	cCCA-RG
V−F	6.21	2.84	3.35
E−C	1.81	1.32	1.53
